WASHINGTON — Same-sex couples will be a part of the proposal for addressing immigration reform that President Obama is scheduled to unveil Tuesday in Las Vegas, BuzzFeed has confirmed with multiple sources familiar with the White House plan.

A Democratic source said: “Same-sex couples will be part of his proposal.” A second source confirmed that, unlike the Senate framework released Monday, same-sex bi-national couples — those with one American and one foreign partner — will be included in the White House principles.

The decision by Obama seeks to remedy what advocates for same-sex couples view as one of the most searing inequalities under the existing federal limit on marriage to one man and one woman: LGBT American citizens simply have no way to confer citizenship on their romantic partners, something that is automatic — if not always simple — for straight couples.
